Organic reference standard, Solvent Yellow 124, analytical standard, Supelco®
Supplier: Merck
Solvent Yellow 124 is a marker dye, generally used in diesel oil as a green colorant, which can be analysed using high performance liquid chromatography method (HPLC). It is mainly used to prevent the misuse of low tax diesel fuel and as to also calculate the adulteration of road fuel with low tax diesel fuel.

n-Heptane, LiChrosolv® for liquid chromatography, Supelco®
Supplier: Merck
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Ethanol ≥99.9% (by GC), LiChrosolv®, gradient grade for liquid chromatography, Supelco®
Supplier: Merck
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in 'gradient grade' as well as 'isocratic grade'. This minimises the gradient effect of the solvent involved.
